About this study

Official title: A Study of the Safety of Ramelteon in Subjects With Moderate to Severe Chronic Obstructive Pulmonary Disease

The purpose of this study is to determine if ramelteon has respiratory depressant effects in subjects with moderate to severe chronic obstructive pulmonary disease.

Read the detailed description

About 30% of the adult population report sleep disturbance and 10% meet diagnostic criteria for chronic insomnia. While 20 -25% of these individuals have primary insomnia the vast majority have an additional condition such as chronic obstructive pulmonary disease. Several studies have looked at this and have estimated that 30% to 48% of the general population is affected at some time in their life with a form of insomnia that goes on for several months, and about one third of those are described as severely affected. Daytime symptoms of insomnia include tiredness, lack of energy, difficulty concentrating and irritability. Recent epidemiologic research focusing on the quality of life has identified significant insomnia related conditions or diseases that relate to work productivity, health care utilization, and risk of depression. Insomnia is associated with diminished work output, absenteeism and greater rates of accidents.

Ramelteon, is being developed as a sleep promoting agent based on agonism of melatonin receptor subtype 1 and 2. Ramelteon is marketed in the United States as Rozerem™ for the treatment of insomnia characterized by difficulty with sleep initiation.

Sleep problems are common in patients with chronic obstructive pulmonary disease. There is evidence that traditional hypnotics can cause adverse respiratory effects in insomniac populations with respiratory disorders, and so the safety and efficacy of new hypnotic agents must be ascertained in this group of patients.

This study will examine if ramelteon has respiratory depressant effects in subjects with moderate to severe chronic obstructive pulmonary disease. Study participation is anticipated to be about 6 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study of Chronic Obstructive Pulmonary Disease, run by Takeda at 8 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 32 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Jun 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mean oxygen saturation during sleep for the entire night measured by pulse oximetry. (time frame: Crossover Period 1 Night 1 and Crossover Period 2 Night 1). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00316992, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Jun 2010.
